This invention relates to a dispensing single use oil container madeof a material capable of being dwtroyed after use, as by burning, and which has particular utility'for storing and dispensing lubricating oils for. motor vehicles. Another object of the invention is to provide 0 a pouring spout of fibrous material containing printed matter thereon which is adapted to be projected into a position where it will-discharge oil into the crank case which will discolor the same to prevent reuse without detection. instrumentalities associated with the container which so disflgure or destroy'the container as to constitute telltales against unauthorized reuse in addition to the discoloration of the combined pouring spout and label, aforesaid.

Another object of the invention is to provide a container fabricated of paper or cellulose prodnets with a light transmitting window by virtue of which the character and/or quantity of the confined oil may be readily ascertained; which container-because of its composition-may easily be destroyed by burning following a single use.

Another object of the invention is to provide the discharge opening of the top with" a transparent window which preferably is disposed eccentrically with respect to the .top and which is capable of being poked inwardly to break the some, which top is provided with a tongue for swinging thebroken transparent window inwardly out ofthe'path of movement of the oil to be discharged from said opening into the spout, aforesaid, and to likewise enlarge said discharge opening to facilitate pouring therefrom.

A still further object of the; invention is to 40 provide a filling aperture in the bottom of the container, as from the top, whereby the oil companies employing the container may fill the same through the bottom and thereafter permanently and irremovably secure a plug, as by swaeins. following the filling operation.

'A' still further object of the invention is to provide indicia on either the top or the trans- J parent window or both. which can be used for measuring the quantity of the confined oil when 7 50, the container is placed in a horizontal position with'the window uppermost.

From another aspect the invention comprehends a fabricated container having three (or more) layers of laminations, the innermost layer 5' being ofproof character but of insuflicient Another object of the invention isto provide moisture-proof character to prevent adherence of a cementitious material thereto; an intermediate protective barrier which is highly absorptive for both grease and water and an outermost layer which is of substantially water repellent character, the various layers being integrated together to form a strong, durable,'leak-proof structure.

The invention comprehends numerous other and additional advantages which will be apparent as to those skilled in the art from a reading of the following specification in conjunction with the drawings attached hereto and forming a part hereof in which:

Referring now more, particularly to the drawings wherein like designating characters indicate corresponding parts 1. indicates my container generally which, as will be hereinafter explained, is made of fibrous material. This container is provided with? a metallic bottom 2 anda metallic top 3 preferably made of tinned iron. The bottom has a filling aperture 4 and a closin-e plug 5. The plug 5 is fitted into the filling aperture after the can has been filled with lubricating oil by the oil companies utilizing the same and is then secured inplace' by expanding it as by a swaging operation according to well known methods usually practiced in the art to increase the inside diameter as at 6, shown particularly in Figure 9, to such an extent that removal would destroy the matrix in which it rests so that if an attempt were made to replace this plug it would not be oil tight and detection could readily be ascertained of its tampered condition. The filling aperture provided by the bottom stamping may be made by punching a hole, say one inch in diameter either centrally or eccentrically and as stated the swaging operation renders the filling aperture impermeable to liquids. As will be appreciated by those skilled in the art, a gasket or compound lining may, if necessary, be interposed between the plug 5 and the'fiange of the closure 2.

The top 3 is provided with a discharge aperture 7 located substantially one sixteenth of an inch inside one of the final edges of the top, from which discharge aperture I provide two lateral cuts 8 and 9, preferably divergingly disposed, which extend approximately one and one-half inch each, said cuts being spaced apart approximately one inch and extend substantially one and one-half inches away from the discharge aperture toward the farther side of the top. These outs define a tongue 10 which is-bendabladownwardly to a vertical .position as will be hereinafter explained, thereby enlarging the size of the discharge aperture and permitting quick discharge of the oil by reason of the fact thatmore air may enter the container.

On the underside of the top is located a strip of nitro-cellulose film 11 which covers both the discharge aperture 4 and the cuts 8 and 9, which film extends at least one quarter of an inch beyond said cuts and is cemented to the under part of the top or instead of cementing it may be adhered by the employment of a solvent or any other means well known in the art whereby said cellulose film may be afiixed to metal.

As is well known, due to the expansibility of liquids, it is obvious that the finished container for practical purposes should never. be filled completely with oil but should comprise an air space over the liquid to avoid bursting when subjected to high temperatures. I find that such an air space may be conveniently of such dimensions cured to the fibre body.

that when the package, aforesaid, is placed horizontally level with the discharge'aperture uppermost the line of its liquid content will fall within the area of the window provided by the discharge aperture with ering. Having thus determined the point to which the liquid will cover the window for a given quantity, I draw or print *a' line on the cellulose window as at 12 or on the top opposite thereto as at 13 and at right angles to the cuts, aforesaid, in r the metallic top, above described, and in such position that when the package is held horizon tally level the liquid content will coincide with the drawn or printed line in the window thus affording the opportunity of estimating the contents of the package without opening it. Of

course, in actual practice, this level indicating line I may be produced automatically in the can factoryon all composite top ends during the process of making the ends and before the ends are se- After the package has been filled and assembled in the manner above described it is capable of usual storage and shipment and may conveniently be opened by pressing down upon the transparent cellulose window covering the aperture and by continuing such pressing effort until portions of the metal forming the tongue beits transparent cellulose covtween the cuts are bent downwardly into:a vertical position as shown clearly in Figure 3. The top thus becomes distorted and incapable of reuse or reconstruction in such a way as to deceive intelligent purchasers. It is to be particularly noted that the transparent window composed of the cellulose film is positioned on the'inside of the top asshown in Figure 5 and that, therefore. the pressure exerted against it improves the adhesion to the top; that when the window is poked inwardly, that portion still adheres to the top but the window is placed entirely out of the path of the oil flow; that the window is afilxed to the package independently of the filling aperture in the bottom of the container and that because of theconstruction and arrangement of the parts ,a receptacle is provided which is incapable of .rial and containing printed matter on the exteri or thereof thereby to cause it to function as an advertising label. This pouring spout has tab portions 15 which encircle the can and are adhered together as at 16 independently of the oil package and thus has a capability of sliding relative to the package into its projected operative position, as shown in Figure 3. Before doing so, however, I preferably provide a seal 17 which must first be broken before sliding the pouring spout to its position shown in Figure 3. Obviously some of the oil as it pours from the spout will be absorbed by the fibrous combined label and pouring spout and will cause the printed matter thereon to be obliterated or discolored.

Consequently, this adjunct constitutes an additional telltale againstreuse and provides a convenient manner of dispensing without a funnel.

The side wall structure disclosed, particularly in Figure 9, is of a fibrous constituency and may be destroyed by burning to avoid the problem of accumulation and the expense of disposal at filling stations as is true in the case where metal cans are employed. This side wall structure is preferably composed of three layers of spirally wound paper designated 17', 18 .and 19. These windings, shown in Figure 8, are so preformed as to separate the abutting unions of each layer, one from the other, and being accomplished by methods well known in the existing arts. For the inner layer 17' I preferably employ a parchmentized paper of approximately five thousandths of an inch in thickness; by parchmentized I mean rag or wood pulp paper which has been subjected to the action of sulphuric acid 59 (fifty-nine) degrees Baum or otherwise treated with an acid, an alkalior cupra-ammonia to render it largely impervious to greasy substances and somewhat impervious to the absorption of moisture. In

forming this inner layer 17' I lap the spirallyfound material by one quarter .of an inch more .or less, as at 2,0, and apply to the outer surface parchmentiaed paper.

mately' fifty thousandths of an inch, such'chip boardbeingpasted with any of the-suitable and well known glues or pastes adaptedto make adhere and to prevent it from too rapi dly'absorb-' ing the paste or glue onthe outer surface of'the I thereupon apply a layer of glazed partially water-proof paper 19, such as paper with a casein coating, over the chip board intermediate layer 18. As a result of these operations there is provided an outer layer which is substantially repellent to the absorption of moisture from the air, a middle layer for bulk and strength. of dense, inexpensive material which has the capabilty of absorbing both moisture or grease if in contact with them and an inner layer which is quite re-' pellent to moisture but not sufficiently so repeladditionally forms a fillet or gasket between the Til its

lent to moisture as to prohibit the use of soluble glues or pastes in cementing it togethe This inner layer 1'1 has applied thereto a'grease repellent glue which completely covers the same and for adhering the bulking intermediatelayer' thereto, the glue filling any pin holes which may exist. It is to be particularly observed that the glue is placed on the outside of the inner layer as shown at 21 and therefore is notvin contacting relation with respect to the lubricating oil confined by the container. Therefore, there is no dangerof the glue or other coating materials which may be employed peeling or entering the body of oil which would materially affect the lubricating properties thereof.

The procedurefor, manufacturing my package is somewhat as follows: If a one quart container is being made I make the spirally wound ,body in such a way that it has an inside diameter of three and one-quarter inches and it is then-cut into lengths of seven and one-half inches. The tops and bottoms are stamped out-of tinned iron or other suitable material having a thickness of approximately fifteenth thousandths of an inch and is so blanked as to fit snugly into the side wall tubing and with such an overlap as to enable the tops and bottoms to spin into permanent aflixaiion by conventional methods well known in the art... Before applying the tops and bottoms of the package Ldip each end of the cut-offtubing in a solution of cellulose acetate having a consistency of thick syrup and commonly known as airplane dope". The dip is merely suflicient to cover theraw edgw of the paper and extends onthe side walls approximately one eighth of an inch. This coating is indicated at 22. Subsequent to this treatment I insert my metal blanks and spin them into permanent aflixation and the cellulose acetate solution performs not only the function of sealing the ratia edges of the layers of paper but paper and the metal blanks, constituting-the'tops and bottoms of the container and serves the purpose of cementing the same to the paper body thereby insuring firmer and liquid-tight afllxation. This is clearly shown in Figure 9.

After the top has been prepared with the discharge aperture 7 and with the cuts or slits 8 and ;9 extending-outwardly therefrom, the nt cellulose window is affixed as aforesaid whereuponlinsertthetopofthepapercontainerand -roll or spin it into permanent afilxation with the cellulose acetate binderto firmly secure the same inplace.

-Havingnowafiixedatoptothepaperbodyof the container, .asdescribed, Iprepare thebottom stampingbypimchingahole ofoneinehindiameter either centrally or eccentrically and separatus which may be employed by the companics utilizing metal containers with no discharge aperture in the top thereof. v

' The parchmentized paper constituting the in-' ner layer 1'1 does not contaminate the oil and being free of protective coatings on .the interior thereof it is not chemically reactive with the oil. Additionally it is important to note that the parchmentized material has very small side wall retention for the oil as the surface tension therec of is quite small as compared with metals or other '95 materials heretofore known to the container art. Pouring, therefore, may be readily accomplished at the filling station in a minimum of time.

Referring now'tothe modification shown in Figures 10 to 13, there is provided an apron 10o shaped label having desirable printed matter thereon and decorated. if desired, which label is designated 23. It is slidably affixed around the package by means of gluing its tabs together as shown at 15 in the preferred form, without however. gluing any portion of the label to the package. The label is provided with a. seal'24 which secures it to a tearing tail 25, which tearing tail is attached to, or provided as a continuation of, a

transparent disc 26 secured to the outside of the 11:)

metallic top and covering the discharge opening 27 and the vent opening 28. In operation the tail "the oil may thereafter be readily discharged into the crank case. p

It will thus be seen that my invention provides a protection to the public for preventing the substitution of another oil oradulterated oil which constitutes a grave problem for the oil industry today and that, furthermore, the package is easily and speedily opened and its contents dischargeable without requiring funnels or special opening tools. It is further to be observed that the problem of disposal by the service stations is materially minimized becausethe paper characteristic of the invention renders it suitable for substantial destruction'byburning as contra-dis- 'tingmshed to the metallic containers now employed which rapidly accumulate and require constant removal to junk yardsor other places of disposal. Furthermore, in point of economy the present device may be made at an expense substantially less than metallic oil containers now commercially employed.

In the foregoing description of my invention I have chosen asingle embodiment purely for the purpose ofillustration in accordance with the patent statutes but I realize that any departure maybe made therefrornwithout departing from the scope of-the invention as comprehended by interpretation of the following claims.

lac

7 Thus, for example, instead of employing parchmentized paper a sheeting of cellulose xanthate, cellulose acetate, cellulose nitrate or synthetic rubber may be used, with a probable lesser degree of efiiciency. Furthermore, the adhesives may be either water soluble or soluble in other solvents such as alcohol, acetone, ar'nylacetate, acetate acid or other well known solvents capable of dissolving carbonaceous substances which form an. ad-

hesive; the character of the inner layer may be also varied and the nature of the coating of the outer layer may be likewise varied. The tops and bottoms of the can may be of any other metal absorbed by the intermediate lamination, said than tinned iron or of: treated paper or any substance capable of forming a union. within the inside walls of the package and being repellent to oils.
